REFLECTOR Box.

Application medoctober 3,' 1921. serial No. 505,063.

To all whom t may concern:

Be it known that L MARTHA MAE HUSTON, a citizen of the United Statesof America, residing at Springfield, in the county of Clark and State ofOhio, Vhave invented newv and useful Improvements in ReflectorBoxes, of which the following is a specificat1on.

The object of the invention 1s to provide a simple and eflicient construction of repact condition; and with these objectsV in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying drawings, wherein:

Figure 1 is a perspective view of a reflector box embodying the invention applied in the operative position to the frame of a sign.

Figure 2 is a similar View showing the same from the rear.

Figure 3 is a detail view of the of the reflector box. Y Y

Figure 4. is a central vertical sectional view.

Figure 5 is a detail view on the plane indicated by the line 5- 5 of Figure 2. Y The' reflector box consists of a'rear wall of angular or V-form constructed of a single blank of material adapted to be arranged as shown in Figure in a fiat condition for packing and storing, and top and bottom walls 11 and 12 of triangular form for closing the space between the rear wall and the plane of the sign frame 13 inwhich may be arranged any suitable vsign filler or diaphragm 141. The material of which the blank forming the rear wall is constructed is preferably pliable or bendableon avertical line 15 to form an angle to dispose re ar wall the terminal or wing portions lof said rear wall in angular relation to properly reflect and concentrate light supplied by any suitable unit, not shown, upon the sign frame ller or diaphragm 14, a Suitable opening or openings 16 being provided in the upper wall to permit of the introduction of suchlight unit or units. The said top and bottom walls whichclose the intervals between rthe upper and lower edges of said rear wall and theplane of the signrframe are provided with Voutwardly directed flanges 17 having slots 18 for engagement by thumb buttons 19 mounted onthe sign frame. The end edges of the rear wall are notched as shown at 20 for engagement with headed studs 21 on the rear surface of the end or vertical members of the sign frame, and the upper and lower edges of the rear wall are provided with outwardly or rearwardly'V directed .flanges 22 for engagement vby the yfolded edges 23 of said upper/and lower walls. v

It will be obvious from theforegoing description that in applying the reflector box to the sign frame the rear wall 10 should first be folded or doubled to the angular form indicated in Figures 1 and 2 so as to Y' engage the .end notches 2O thereof with the headed 'studs-21, after which the top and bottom walls should be interlocked at their rear edges with the anges 22 of said: rear.

wall and then secured by engaging the slots 18 thereof with the thumb buttons 19 whereby the reflector box structure is Vsubstantially secured to the frame of the sign.V

sheet of material folded on al1-intermediate line provides for the spring'action on .theV part of the rear wall to retain itsnotchesY 2() in engagement with the headed studs when the wall is attachedand thus provides against rattling if the device is carried on Ya movlng vehicle. Were the rear wall-coin posed of two sections hingedly connected together atthe bend, the top and bottom walls would have tobe relied on solely to keep the notches in engagement Vwith the studs andY there would be likelihood of-loose connections with attendant rattling.

. Having described the invention7` what is claimed as Ynew and useful is A reflector box for signs-consisting of rear wall formed with a single, `blank of sheet material and bent on anV intermediate` vertical line to form an angle to disposethe terminal portions of the back in angular relation to properly reliect and concentrate light supplied by a light unit, a frame havingron its rear side edges headed studs with engagement with the edges of the rear Wall which notches formed in the side rear edges at their rear ends `.find detachably secured of the back Wall engage, the material of to the frame at their front edges. 10`
